[Help] Music album cover art - permission problem

Hello everyone, I noticed that a lot of my music does not get any album art even though they correctly identified with MusicBrainz and the albums do have a cover on them there. Jellyfin does not have write permissions in the data directly where the music is, only read permissions. Though I would have expected that jellyfin uses the metadata folder for cover images not already present there. The reason Jellyfin doesn't have write permissions is that the folder is managed by nextcloud and that creates files with 750 so only read access for the group and jellyfin uses the group Does anyone know how I could solve the issue?

Log when trying to identify an album which should have edited the image:

[WRN] Unable to delete "/{{REDACTED}}/files/Musik/Everglow/Last Melody [Single]/Folder.jpg" System.UnauthorizedAccessException: Access to the path '/{{REDACTED}}/Musik/Everglow/Last Melody [Single]/Folder.jpg' is denied. ---> System.IO.IOException: Permission denied --- End of inner exception stack trace --- at System.IO.FileSystem.DeleteFile(String fullPath) at MediaBrowser.Providers.Manager.ItemImageProvider.PruneImages(BaseItem item, IReadOnlyList`1 images)

I tried giving Jellyfin write permissions on the folder and when identifying an album and it just decided to delete all tracks...

from the log after giving write permissions:
